Rare turnkey duplex just 3 blocks to the sand in the highly sought-after North Hermosa Beach Sand Section. 426 & 428 25th Street offer an exceptional combination of location, condition, proven rental history and flexibility, with two extensively renovated 1-bedroom, 1-bath residences ready for immediate occupancy or rental. Ideal for investors, 1031 exchange buyers, owner-users or those looking for a permanent South Bay beach retreat. Live in one and rent the other, lease both as highly desirable long-term rentals, or explore potential short-term/Airbnb-style rental use subject to City of Hermosa Beach registration, permitting, approval and applicable regulations. For frequent travelers or those who split time between locations, this is an incredible opportunity to maintain a coastal home base while generating income from the second residence. Both units have been extensively updated with high-end stainless appliances, quartz countertops, wide-plank luxury vinyl flooring, beautifully renovated bathrooms, individual efficiency washer/dryers and mini-split heating and air conditioning in both the bedrooms and living areas. The open and bright upper residence features expansive windows and sliders opening to a private deck, while the property also offers extensive landscaping and an outdoor surf shower-perfect after a day at the beach. Previously leased to longer-term tenants, the upper unit rented for $4,500 per month and the lower for $3,800 per month, demonstrating the strong rental appeal of this exceptional location. Both units are being delivered vacant, giving the new owner tremendous flexibility from day one. Beyond its current use as a duplex, the owners have consulted with architects and an attorney regarding the potential to convert the property back into a larger single-family residence. The property is also offered in the residential MLS under MLS #SB26173303; buyers should independently investigate and verify any potential conversion. Just moments from the beach, The Strand, surfing, volleyball, restaurants, shops and all that makes Hermosa Beach one of the South Bay's most desirable coastal communities, this is the rare extensively renovated, truly turnkey duplex offering immediate enjoyment, multiple potential uses and outstanding long-term possibilities.
